Hi, this problem had bothered me for a very long time one month ago. I used a flash disk to host the root partition to solve the problem. But after a month, I find the flash disk was easily lost data even with readonly all the time. So I moved back to hard disk. But the unionfs solution seems works well to solve this problem:
I'm using ubuntu AMD64, I found that /etc/mtab and /etc/hosts was access all the time. So if we mount etc into memory, the hard disk click will stopped immediately. Put the following lines into the proper position of /etc/init.d/mountkernfs.sh: /bin/mount -v -n --bind /etc /unionfs/ro/etc /bin/mount -v -n -t unionfs -o dirs=/unionfs/mem/etc=rw:/unionfs/ro/etc=ro unionfs /etc And you also need to put another script in rc0.d and rc6.d to save the changes in etc. And one in rcS.d to restore the changes. Otherwise all changes to etc will lost after a reboot. -- hard disk being accessed every 4 sec. https://bugs.launchpad.net/bugs/17878 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
